Smartphone Link
Smartphone connectivity simplifies configuration of settings, and Auto Time Adjust ensures that time settings are always correct no matter where you
happen to be.
The watch can also be configured to obtain altitude information using a smartphone's GPS and automatically correct its own altitude readings. When the watch connects with a phone, it also acquires latitude and longitude information, which is used to calculate the sunrise and sunset times for your current location.
Quad Sensor System
The Quad Sensor system uses compact sensors that make it possible to pack compass, altitude/barometer, and temperature measurements, along with an accelerometer that keeps track of your step count, into a compact configuration.
Compass Bearing
Display your current position and your recorded movement log on a high-definition color map while you measure your activity. This allows you to check your current position without having to get out your smartphone. Use this feature in situations such as when you want to challenge yourself with new courses or when you want to run while traveling.
Barometric Pressure / Alititude
Import GPS log data (such as for past routes or recommended routes from ViewRanger) into the watch by using Google DriveTM, and set these routes for running. Check your route on the map while you run as a form of simple navigation.
Temperature / Accelerometer
Save the routes on which you travel during your activities as activity data. You can use markers to record checkpoints for locations such as places where water is available, and create your own running routes. You can then share these routes with others.
Additional Features
(Wireless linking with Bluetooth® devices)
Requires installation of an app on your phone.
App Linking, Simplified Setups
- Trekking Log
Altitude information acquired by the watch and GPS information acquired by your phone are automatically recorded by the app. You can plot manually recorded altitude points on your route. - Step Tracker
The app takes upgrades and downgrades into consideration when calculating calories burned by referencing altitude changes, and records the results in an Activity Log - Location Indicator
A watch button operation can be used to record your current location on the app. After that, the second hand of the watch will indicate the bearing and the digital display will show the distance to the recorded location. - Mode/Display Switching Customization
You can use the app to enable or disable each mode, and even specify the sequence used for enabled mode access. This means you can customize mode operations to suit your needs and convenience. - Auto Altitude Correction (4 times/day)
The watch uses GPS information acquired by your phone to correct its altitude measurements automatically - Auto Time Correction (4 times/day)
- More than 300 World Time Cities
- Alarms, Timer
- Phone Finder
